DDA111, one mixing circuit + one direct circuit

Double circulation unit

DDA100

Double circulation unit Series DDA100 is a compact unit for two separated heating circuits. One with a direct supply, and one with a mixing function. Equipped with two high efficient pumps, a valve with progressive characteristic, actuator, ball valves with thermometers, manifold with by-pass function and a insulation shell. Double circulation unit is a perfect choice for heating pumps, and boilers which are working with radiator and/or underfloor heating.

Compact, all in one design
Easy to install
Manifold with option of hydraulic separation easily set with a screw
Check valve integrated into ball valves return line
High flow rate
Possible to upgrade with upgrade kit
Quick-fit actuator
